Just recently, I found not only a dub of Shakugan no Shana by Geneon, but also a dub of SnSII by Animax, on the internet. Since they're by different companies, their voices are different.

Let me make a comparison with the episodes I've watched so far:

Shana's voice in the Animax dub is slightly better than in the Geneon dub, for me at least, since she's really supposed to sound like a 12 year old.

As for Yuji and Sydonay, either voice works.

But for everyone else, go with the Geneon dub.

By the way, Alastor in the Animax dub sounds a lot like the dubbed voice of Ryukendo's talking weapon.

On a side note, I found another extremely rare specimen on another site: a dub of "Nadia: Secret of Blue Water", which was made before I was even born. Btw, did you know that the main characters were voiced by actual kids, and they did a much better job than a lot of dubbers in other anime in this decade.

Oh, and I just found out on Wikipedia that Shakugan no SHana III is coming on October this year, along side To Aru Kagaku No Railgun! This is gonna be the best Winter season of anime ever!!!

EDIT: Oops! I got so worked up I didn't notice what was coming out this October was actually just another OVA of Shakugan no Shana, called Shakugan no SHana S. But the thing about Railgun is still true.

False alarm. Forgive me if you fainted in happiness, then again in disappointment.

Still, it's gonna be a real fun Winter season of anime this year!
